de la Rosa talking up HRT.. all very good but when will they bring some upgrades? Apart from the forced nose change, the car is the same as 2010.
If that was the case they'd be a lot further back than they are...wouldn't be able to race or outqualify Marussia for starters. Their main problem right now is tyre degradation.
Perez-Sala doesn't have enough staff (just 75, Caterham have at least double that and a lot more funding) to both design the 2013 car and work on major upgrades in-house at the same time, so they're doing the former. Whatever Holzer in Germany produced for them is relatively minor.
